ECU & TCU Remapping
Workshop-based services plus mobile dealers across South Wales.
Performance, economy and drivability — done responsibly
We provide all stages of tuning, from economy tuning to Stage 3 full custom conversions, towing maps and speed limiters.
Specialists in performance and economy tuning on mainstream cars and 4x4's. We can provide economy tuning, Stage 1–3 upgrades, towing maps and speed limiter installation. With a specialist development program and dealers nationwide, we can offer services in most places.
Performance and economy tuning for light commercial vans. Many vans share engine variants with mainstream cars, so the tuning potential is similar. We can also provide towing maps, speed limiters and custom upgrades.
Solutions that help reduce running costs: economy tuning, limiter installation and (where used) telematics support to help control fleet fuel spend.
Performance and economy tuning on agricultural vehicles. Increased power/torque improves productivity, reduces work time, and can help avoid replacing machinery.
Factory ECU maps are often detuned for emissions, climate and product-range targets. Remapping refines fuel, torque delivery and throttle response to safely unlock more power (bhp) and torque (Nm), improve low-end pull and smooth issues like snatchy throttle or low-rev surging.
Performance and economy tuning for marine engines (petrol and diesel). With most applications using electronic injection, we can tune jet skis right up to super yachts.
